Description

Lifting device

The present invention provides a lifting device, in particular to a lifting device capable of reducing the floating phenomenon caused by the use of a gas bar lifting object to achieve stable lifting of the object.

Press, general objects, such as tables and chairs, have a fixed height. In order to meet the needs of users of different ages, the height of the object can be adjusted up and down. The lifting device for adjusting the height of the lifting object on the market is combined with an object. In the lower part, the lifting device includes a base fixed to the bottom surface of the object, a top end fixed to the upper seat of the gas pressure bar, and a base fixed to the bottom end of the gas pressure bar, and the telescopic expansion of the gas pressure bar can be operated Adjusting the height of the object; however, when the object is large in area, since the gas bar is supported at the center of the object, there is no other supporting structure, and when the gas bar is displaced up and down, the object will float left and right. Phenomenon, so whether it is rising or falling, the object can not maintain a flat state, but will produce a floating phenomenon, and the stability is not good.

The main purpose of the present invention is to provide a lifting device, comprising a top seat, a gas pressure bar installed under the upper seat, two support bars extending downward from the upper seat, and a socket for connecting the gas pressure bar and the two support bars Under the seat.

Each of the support rods has an outer peripheral surface, at least one set of collars connected to the outer peripheral surface, and a plurality of spheres movably mounted on the collar and attached to the outer peripheral surface, and a fixed a stop at the bottom end of the outer edge surface for preventing the at least one set of rings from coming off.

The lower seat has a standing stand, a through hole penetrating the upright stand for fixing the gas bar through the set, and two sleeves disposed in the upright stand and for the two support rods to penetrate; each of the sleeves The sleeve has an inner rim surface that abuts the plurality of spheres.

The two support rods are used to assist the gas pressure rod to support an object, so that the object can maintain a stable displacement state during the lifting process, thereby reducing the floating phenomenon of the object, and by using the majority of the balls, the two support rods can be The two sleeves have smooth and unobstructed upward and downward movement and good stability.

1 is a perspective view of the present invention; FIG. 2 is an exploded perspective view of the present invention, showing a relative position of the upper seat and the lower seat; and FIG. 3 is a combined sectional view of the present invention, showing that most of the balls are attached The state of the outer surface of the support rod and the inner surface of the two sleeves; and the fourth diagram is another sectional view of the present invention, showing that the two support rods support an object in a rising state.

First, please refer to the first and second figures. The lifting device of the present invention is mounted under an object A, and includes a seat 10 fixed to the bottom surface of the object A, and a gas pressure bar 20 installed under the upper seat 10. The upper seat 10 has a support rod 30 extending downwardly, and a socket 40 for tying the gas rod 20 and the lower support rod 30.

The gas pressure bar 20 has a piston rod 21 connected to the upper seat 10 and a cylinder tube 22 for socketing the piston rod 21.

The two support rods 30 are located on two sides of the gas pressure bar 20, and each of the support rods 30 has an outer edge surface 31, at least one set of collars 32 connected to the outer edge surface 31, and most movable loads. a ball 33 disposed on the collar 32, and a stop 34 fixed to the bottom end of the outer edge surface 31 for preventing the at least one set of rings 32 from coming off.

The lower seat 40 has a standing stand 41, a through hole 42 penetrating the upright stand 41, and two sleeves 43 disposed in the upright stand 41. Wherein, each sleeve 43 has an inner edge surface 44, and the upright table 41 extends downwardly to a chassis 45.

Referring to FIG. 3 , in the assembly of the present invention, the cylinder tube 22 of the gas pressure bar 20 penetrates the through hole 42 . The bottom end of the cylinder tube 22 is fixed to the chassis 45 , and the two support rods 30 penetrate the two sets. In the cylinder 43, the plurality of balls 33 are attached to the outer edge surface 31 of the support rod 30 and the inner edge surface 44 of the sleeve 43.

Referring to FIG. 4 , when the object A is lifted and lowered, the piston rod 21 is controlled to expand and contract in the cylinder tube 22 , and the two support rods 30 are movably attached to the inner edge surface 44 and the outer edge by using the plurality of balls 33 . The surface 31 allows the two support rods 30 to smoothly slide up and down the two sleeves 43, thereby achieving the purpose of stably supporting the object A and reducing the floating of the object A.

It should be noted that the object A can be a table when implemented, and the object A and the lifting device together form a table.

Therefore, the present invention is composed of the above structure, and compared with the prior art, it has the following advancement:

1. The two support rods 30 extending from the upper seat 10 are used to assist the air pressure bar 20 to support the object A, so that the object A can maintain a stable displacement state regardless of the ascending or descending, and the object A is lowered. phenomenon.

The two support rods 30 can utilize the active majority of the balls 33 mounted on the at least one set of rings 32 to enable the two support rods 30 to smoothly and unimpededly move up and down in the two sleeves 43. , good stability.

Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present invention. Any newcomer to this art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the scope of the appended claims, and its legal equivalents are not limited to the foregoing description.
